The fire began just before 1 p.m. Thursday on Soda Bay Road at Golf Drive, in the Black Forest.
Cal Fire said its investigators were immediately dispatched to the Golf fire and began working to determine the origin and cause of the fire.
After “a meticulous and thorough investigation,” Cal Fire said it has determined that the Golf fire was caused by an improperly discarded cigarette.
When needing to discard a cigarette, Cal Fire reminds members of the public to use a deep, sturdy ashtray and place it away from anything that can burn.
“Do not discard cigarettes in vegetation such as mulch, potted plants or landscaping, peat moss, dried grasses, leaves or other things that could ignite easily,” Cal Fire said.
“Before you throw away any cigarette butts and ashes, make sure they are out. Dousing them in water or sand is the best way to do that. Never throw cigarettes out of vehicles, always discard them in an ashtray or a container designed for cigarette disposal,” the agency’s report on the fire’s cause said.
Cal Fire’s latest report on the fire’s conditions put it at 20 acres with containment at 80 percent.
One firefighter on the incident has suffered a minor injury, officials said.
No structures have been destroyed or damaged.
All evacuations were lifted on Friday, and on Saturday the Lake County Sheriff’s Office said the road closures on Soda Bay Road in Buckingham were lifted as of noon, but motorists were asked to remain alert for emergency personnel and equipment that may still be working in the area.
Crews on Saturday continued to construct control line and extinguish hot spots within the fire
Area, Cal Fire said.
The firefighting work has been aided by better weather conditions, including higher humidities and lower temperatures, officials said.
Cal Fire said overnight winds tested the control lines with no extension outside the perimeter.
